Embodiment 1

[0020] Weigh 4g calcium carbonate, 10.32g calcium hydrogen phosphate and 28.64g sodium chloride, mix them in a ball mill at 300 rpm for 3 hours, take them out and put them in an alumina crucible, and put the alumina crucible in a high-temperature furnace. Raise the furnace temperature to 1000°C in 4 hours, keep it warm for 1 hour, and turn off the power. When the temperature in the furnace drops to room temperature, take out the product, put it in a mortar and grind slightly to obtain a dispersed powder. Add distilled water to the powder, fully stir and filter, and repeatedly wash 3 times. Put the powder in an oven and dry at 100°C for 24 hours to obtain chlorapatite whiskers. The obtained chlorapatite whiskers The diameter is 3-40μm and the length is 10-300μm.

Embodiment 2

[0022] Weigh 4g calcium carbonate, 10.32g calcium hydrogen phosphate and 14.32g potassium chloride, mix them in a ball mill at 300 rpm for 3 hours, take them out and put them in an alumina crucible, and put the alumina crucible in a high-temperature furnace. Raise the furnace temperature to 1150°C for 4 hours, keep it warm for 1 hour, and turn off the power. When the temperature in the furnace drops to room temperature, take out the product, put it in a mortar and grind slightly to obtain a dispersed powder. Add distilled water to the powder, fully stir and filter, repeat washing 5 times, put the powder in an oven at 120°C for 24 hours to obtain chlorapatite whiskers, and the obtained chlorapatite whiskers The diameter is 1-30μm and the length is 5-200μm.

Abstract

The invention relates to a preparation method of a chlorohydroxyapatite whisker, and belongs to the fields of chemistry and materials. The method comprises the steps: with calcium carbonate and calcium hydrophosphate as calcium and phosphorus source materials and an alkali metal chloride as a fused salt, obtaining the chlorohydroxyapatite whisker material by controlling the composition of the fused salt, the ratio of the fused salt to the calcium and phosphorus mixed material, and the reaction temperature. The diameter of the obtained chlorohydroxyapatite whisker ranges from 0.5 microns to 40 microns, and the length of the chlorohydroxyapatite whisker ranges from 5 microns to 300 microns; the chlorohydroxyapatite whisker is mainly used for reinforcing and toughening ceramics and high molecular biological materials; therefore, the chlorohydroxyapatite whisker has the value of wide application.

Description

Technical field [0001] The invention relates to the fields of chemistry and materials, in particular to a preparation method of chloroapatite whiskers. Background technique [0002] The human body contains more than 60 elements. The four elements of oxygen, carbon, hydrogen, and nitrogen account for 96% of the total body, and the seven elements of calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium account for 3.95%. The above eleven elements account for 99.95% of the total human body and are called essential macro elements in the human body. The salt in human bone tissue is mainly calcium phosphate, followed by carbonate, citrate, and a small amount of chloride and fluoride. Phosphorus, calcium, and chlorine are all essential nutrients for animal and human growth. [0003] The main inorganic component of human and animal bone tissue is hydroxyapatite, and a small amount of apatite containing carbonate and chloride ions. There are a wide range of isomorphic su...
